VPN related introduction

VPN is commonly used to connect, large enterprises or groups and groups of private networks communication method. The message of the virtual private network transmits the intranet’s network information through a common network architecture (for example, the Internet). It uses the Tunneling Protocol to achieve privacy, sender authentication, message accuracy and other private message security effects. This technique can be used to send reliable and secure messages over insecure networks (eg, the Internet). Note that encrypting messages or not is controllable. Unprotected virtual private network messages Internet still have the risk of being stolen.

History
In the 1990s, computers on computer Internet were interconnected by very expensive dedicated lines and / or dial-up lines. Depending on the distance between sites, it can cost thousands of dollars (56kbps connection) or tens of thousands of dollars.

In order to avoid leasing more than one dedicated line to connect to the Internet, since the virtual private Internet can reduce network expenses, users can connect exchange private data securely, virtual private networks have become popular, and expensive private lines become redundant

VPN security introduction：
Secure virtual private networks use cryptographic tunneling protocols to provide confidentiality by blocking sniffing and sniffing and also to connect sender authentication to prevent identity forgery while providing message integrity by preventing connect Internet from being modified.

Some virtual private networks do not use encryption to protect data. Although virtual private networks generally provide security, unencrypted virtual private networks are not strictly “safe” or “trustworthy.” For example, a connect created between two hosts through the GRE protocol connect to a virtual private network, but neither is secure nor trustworthy.

In addition to the GRE protocol examples above, local plaintext tunneling protocols include L2TP (without IPsec) and PPTP (when not using Microsoft Point-to-Point Encryption (MPPE)).
